System and Method of Determining a Position of a Remote Object via One or More Image Sensors

ABSTRACT

In one or more embodiments, one or more systems, methods and/or processes may determine a location of a remote object (e.g., a point and/or area of interest, landmark, structure that “looks interesting”, buoy, anchored boat, etc.). For example, the location of a remote object may be determined via a first bearing, at a first location, and a second bearing, at a second location, to the remote object. For instance, the first and second locations can be determined via a position device, such as a global positioning system device. In one or more embodiments, the location of the remote object may be based on the first location, the second location, the first bearing, and the second bearing. For example, the location of the remote object may be provided to a user via a map. For instance, turn-by-turn direction to the location of the remote object may be provided to the user.

This Application claims priority to and is a Continuation of U.S. patent application Ser. No. 13/837,853, filed on 15 Mar. 2013, titled “System and Method of Determining a Position of a Remote Object”, which is hereby incorporated by reference.

BACKGROUND

1. Technical Field

This disclosure relates generally to the field of navigation systems, and, more specifically, this disclosure pertains to the field of determining a position of a remote object via one or more mobile devices.

2. Description of the Related Art

In the past, determining a position of an end of a starting line of a sailboat race included maneuvering and/or positioning a vessel to a point proximate to the end of the starting line. As illustrated in FIG. 1A, a vessel 1010 may include a position device (e.g., a global positioning system (GPS) receiver and processor) that may determine a position of an antenna included in or coupled to the position device, where vessel 1010 is positioned proximate to staff 1210 which is used to form a first end of a starting line 1310. As shown, staff 1210 may be mounted on a vessel 1110 (e.g., a race committee boat). A second end of starting line 1310 is formed using object 1220 (e.g., a buoy, a floating tetrahedron, a vessel, etc.). As illustrated in FIG. 1B, vessel 1010 is positioned proximate to object 1220 which is used to form the second end of starting line 1310. After two positions respectively corresponding to the two ends of starting line 1310 are determined, a distance to starting line 1310 may be determined from another position of vessel 1110.

One or more issues may be or become problematic when utilizing one or more systems and/or methods of the past. In one example, a starting area may be “crowded”. For instance, the starting area may be “crowded” with multiple vessels, such as vessels 1010-1018, and an amount of time may not exist for one or more of the multiple vessels 1010-1018 to determine the two ends of the line. In a second example, one or more ends of the starting line may be moved by the race committee, and an amount of time may not exist for one or more of the multiple vessels 1010-1018 to determine the two ends of the line. For instance, the race committee may move object 1220 from a first position to a second position and start a race shortly (e.g., one to five minutes) after moving object 1220 from the first position to the second position. In another example, multiple starts may occur, and a vessel may not be allowed near the starting area until the vessel's starting sequence.

Also in the past, determining a position of a point and/or area of interest (e.g., a landmark, a structure that “looks interesting”, a remote object, etc.) at a distance was not possible for some (e.g., tourists, non-locals, etc.). For example, a family could be driving along a highway and spot a structure at a distance. Not knowing where and what the structure at the distance is, the family may not know where the structure at the distance is. For instance, structure 2010, as illustrated in FIG. 2, may not be known and/or its location may not be known to some.

It should be understood, however, that the drawings and detailed description thereto are not intended to limit the disclosure to the particular form disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents and alternatives falling within the spirit and scope of this disclosure. Moreover, some of the drawings and/or illustrations are not drawn to scale and are drawn and/or illustrated to show and/or demonstrate by way of example as may be expressed via drawings and/or illustrations.

DETAILED DESCRIPTION

In one or more embodiments, one or more systems, methods, and/or processes described herein may compute a position of a remote object. For example, computing the position of the remote object may be based on a first bearing at a first position and a second bearing at a second position. In one or more embodiments, a bearing to the remote object may be based on an angular difference between a geographic position and the remote object. In one example, the bearing to the remote object may be based on an angular difference between a geographic pole (e.g., a geographic north pole, a geographic south pole, etc.) and the remote object. In another example, the bearing to the remote object may be based on an angular difference between a magnetic pole (e.g., a magnetic north pole, a magnetic south pole, etc.) and the remote object.

In one or more embodiments, computing the angular difference between the geographic pole and the remote object may include computing an angular difference between a magnetic pole (e.g., a magnetic north pole, a magnetic south pole, etc.) and the remote object. For example, a bearing device may be oriented with respect to the remote object, and one or more measurements of a magnetic field of a planet may be utilized in computing the angular difference between the magnetic pole and the remote object. In one or more embodiments, the magnetic pole may not be at a same position as the geographic pole, and a declination angle and the angular difference between the magnetic pole and the remote object may be utilized in computing the angular difference between the geographic pole and the remote object.

In one or more embodiments, a declination angle may depend on one or more of a position and a time, among others. In one example, a declination angle at a first position may be different from a declination angle at a second position. In another example, a declination angle at a first point in time may be different from a declination angle at a second point in time. For instance, one or more positions of respective one or more magnetic poles of a planet may change over a period of time transpiring.

In one or more embodiments, a position of a remote object may be computed without interrogating the remote object with sound waves or electromagnetic waves. In one example, a position of a remote object may be computed without interrogating the remote object with sonar. In another example, a position of a remote object may be computed without interrogating the remote object with radar (e.g., laser radar, microwave radar, etc.). In one or more embodiments, a position of a remote object may be computed when the remote object is position outside a constellation of ranging signal generating devices. For example, a position of a remote object outside a constellation of pseudolites or satellites may be determined from a position within the constellation of pseudolites or satellites.

In one or more embodiments, a position of a remote object may be determined from various positions. In one example, a position of a remote object may be determined from positions on land. In a second example, a position of a remote object may be determined from positions on water (e.g., sea, ocean, river, lake, etc.). In a third example, a position of a remote object may be determined from positions in air (e.g., from an aerial vehicle, such as a glider, an airplane, a helicopter, etc.). In another example, a position of a remote object may be determined from positions in space (e.g., from a satellite, a space station, a space ship, a space vehicle, etc.).

In one or more embodiments, one or more mobile devices may be utilized in computing the position of the remote object based on the first bearing at the first position and the second bearing at the second position. In one example, a position device (e.g., a global position system device) may be utilized in computing one or more of the first position and the second position, among others. In another example, a bearing device may be utilized computing one or more of the first bearing and the second bearing, among others. For instance, the bearing device may be or include an electric compass that may transform an orientation of the bearing device into an angular difference between a magnetic pole and the orientation of the bearing device.

In one or more embodiments, one or more systems, methods, and/or processes described herein may compute a first plane that includes the first position, the position of the remote object, and an origin and may compute a second plane that includes the second position, the position of the remote object which may be utilized in computing the position of the remote object. For example, one or more systems, methods, and/or processes described herein may compute an intersection of the first plane and the second plane, where the intersection of the first plane and the second plane includes a line that includes the position of the remote object. For instance, the position of the remote object may be on a planet (e.g., Earth), and the intersection of the first plane and the second plane may include the position of the remote object. In one or more embodiments, computing the intersection of the first plane and the second plane may include computing a line and/or a vector. For example, computing the vector of the intersection of the first plane and the second plane may include computing an angular latitude measure and an angular longitude measure. For instance, the position of the remote object may be on the planet (e.g., at a radius from a center of the planet) and at the angular latitude measure and at the angular longitude measure.

In one or more embodiments, one or more devices and/or systems described herein may communicate, utilizing one or more signals, in one or more of a wireless fashion and a wired fashion. In one example, the bearing device may be a handheld bearing device that may communicate bearing information via one or more signals in a wireless fashion or in a wired fashion.

For instance, an accelerometer device may transtform one or more rates of change in velocity into one or more machine-readable (e.g., computer-readable) signals. In another example, an accelerometer device may transform one or more phenomena of weight (e.g., one or more forces of gravity upon an object associated with a mass) associated with a test mass at rest in a frame of reference of the accelerometer device into voltages, currents, and/or numbers. In one instance, the accelerometer device may transform one or more phenomena of weight associated with a test mass at rest in a frame of reference of the accelerometer device into one or more machine-readable (e.g., computer-readable) signals.

In one or more embodiments, a difference between the first acceleration and the second acceleration may be utilized in determining an angle between the axis associated with the accelerometer device and a vector from the origin. For example, the difference between the first acceleration and the second acceleration may be utilized in determining an angle of tilt (e.g., angle of pitch and/or angle of roll) of the accelerometer device and/or a structure that is coupled to the accelerometer device.

Turning now to FIG. 28A, an exemplary method of determining a plane that includes a determined position and a pole is illustrated, according to one or more embodiments. At 28010, a position may be determined. In one example, position 6010 (as illustrated in FIG. 6A) may be determined. In a second example, position 6015 (as illustrated in FIG. 6B) may be determined. In a third example, position 6017 (as illustrated in FIG. 6C) may be determined. In a fourth example, position 9010 (as illustrated in FIG. 9A) may be determined. In a fifth example, position 9015 (as illustrated in FIG. 9B) may be determined. In another example, position 9017 (as illustrated in FIG. 9C) may be determined.

In one or more embodiments, a plane may be associated with, may correspond to, and/or may be described by a vector that is normal to (e.g., perpendicular to) the plane. For example, a plane may be described as a·x+b·y+c·z=0, and a vector that is normal to (e.g., perpendicular to) the plane may be (a,b,c).

At 28020, a vector, based on the position, may be computed. For example, the vector may be computed via a vector cross product of a vector corresponding to the determined position and a vector corresponding to a pole (e.g., a north pole, a south pole, etc.). In one or more embodiments, the computed vector is normal to a plane that includes the determined position and the pole, and the computed vector may be utilized to describe the plane that includes the determined position and the pole.

Turning now to FIG. 28B, an exemplary method of determining a plane that includes a determined position, according to one or more embodiments. At 28050, a position may be determined. In one example, position 6010 (as illustrated in FIG. 6A) may be determined. In a second example, position 6015 (as illustrated in FIG. 6B) may be determined. In a third example, position 6017 (as illustrated in FIG. 6C) may be determined. In a fourth example, position 9010 (as illustrated in FIG. 9A) may be determined. In a fifth example, position 9015 (as illustrated in FIG. 9B) may be determined. In another example, position 9017 (as illustrated in FIG. 9C) may be determined.

At 28060, a vector corresponding to and/or associated with the position may be altered. In one example, the position may include a spherical coordinate form that may be utilized for the vector corresponding to and/or associated with the position. For instance, a position device may provide the position in a spherical coordinate form (e.g., latitude and longitude) that may be utilized for the vector corresponding to and/or associated with the position. In another example, the position may be converted to a spherical coordinate form that may be utilized for the vector corresponding to and/or associated with the position. For instance, the position may include a Cartesian coordinate form and may be converted into a spherical coordinate form that may be utilized for the vector corresponding to and/or associated with the position. In one or more embodiments, altering the vector corresponding to and/or associated with the position may include setting a component of the vector. For example, the vector corresponding to and/or associated with the position may include (ρ,θ,φ), and the φ component may be set to

$\frac{\pi}{2},$

producing

$\left( {\rho,\theta,\frac{\pi}{2}} \right).$

At 28070, a vector normal to the altered vector corresponding to and/or associated with the position may be determined. In one example, a vector normal to the altered vector corresponding to and/or associated with the position may be determined via adding ninety degrees or by

$\frac{\pi}{2}$

radians to the θ component of the altered vector. For instance, adding ninety degrees or by

$\frac{\pi}{2}$

radians to the θ component of the altered vector may produce

$\left( {\rho,{\theta + \frac{\pi}{2}},\frac{\pi}{2}} \right).$

In another example, a vector normal to the altered vector corresponding to and/or associated with the position may be determined via subtracting ninety degrees or by

$\frac{\pi}{2}$

radians from the θ component of the altered vector. For instance, subtracting ninety degrees or

$\frac{\pi}{2}$

radians from the θ component of the altered vector may produce

$\frac{\pi}{2}$

In one or more embodiments, adding or subtracting ninety degrees or

$\left( {\rho,{\theta - \frac{\pi}{2}},\frac{\pi}{2}} \right).$

radians to the θ component of the altered vector may produce a vector that is normal the vector corresponding to and/or associated with the position and that is included in a plane that includes equator 6110 of sphere 6000. For example, at least one of

$\left( {\rho,{\theta + \frac{\pi}{2}},\frac{\pi}{2}} \right)\mspace{14mu} {and}\mspace{14mu} \left( {\rho,{\theta - \frac{\pi}{2}},\frac{\pi}{2}} \right)$

may be utilized to describe a plane that includes the determined position and a pole of sphere 6000. For instance, the at least one of

$\left( {\rho,{\theta + \frac{\pi}{2}},\frac{\pi}{2}} \right)\mspace{14mu} {and}\mspace{14mu} \left( {\rho,{\theta - \frac{\pi}{2}},\frac{\pi}{2}} \right)$

may be converted into a Cartesian coordinate system, where the at least one of

${\left( {\rho,{\theta + \frac{\pi}{2}},\frac{\pi}{2}} \right)\mspace{14mu} {and}\mspace{14mu} \left( {\rho,{\theta - \frac{\pi}{2}},\frac{\pi}{2}} \right)},$

converted into a Cartesian coordinate system, may be utilized to describe a plane that includes the determined position and a pole of sphere 6000.

Turning now to FIG. 29, an exemplary method of determining a position of an object is illustrated, according to one or more embodiments. At 29010, a first bearing to an object may be determined. In one or more embodiments, user 5010 may align bearing device 5110 with the object. For example, user 5010, at a first position (e.g., position 6010), may align bearing device 5110 with object 3210. In one or more embodiments, bearing device 5110 may determine a first angle of the object, with respect to a magnetic pole (e.g., a magnetic north pole). In one example, the first angle may be utilized as the first bearing. In another example, the first bearing may be based on the first angle, determined via the bearing device, and an angle of declination. For instance, the first bearing may be computed as a sum of the first angle, determined via the bearing device, and the angle of declination.

At 29020, a first position may be determined. For example, position device 15310 may determine the first position (e.g., position 6010). In one or more embodiments, the first position corresponds to the first bearing. In one example, the first bearing to the object and the first position may be determined simultaneously. In a second example, the first bearing to the object and the first position may be determined concurrently. For instance, at least one portion of determining the first bearing to the object and at least one portion of determining the first position may occur during an amount of time transpiring. In another example, the first bearing to the object and the first position may be determined serially such that an amount of time transpiring does not adversely affect an accuracy of determining the position of the object. For instance, determining the first position may be determined within a foot or two of determining the first bearing. In one example, a system that determines the position of the object may be moving. For instance, the system that determines the position of the object may be moving at a first speed. In another example, a system that determines the position of the object may be stationary.

At 29030, a first vector that is normal to an origin, the object, and the first position may be determined. For example, a vector 30110, as illustrated in FIG. 30A, may be determined as the first vector. For instance, the origin, the object (e.g., at position 6210), and the first position (e.g., position 6010) may be a basis for a plane 30010, which is illustrated in FIG. 30A as an intersection with sphere 6000. In one or more embodiments, determining the first vector may include utilizing the first bearing. For example, plane 30010 may intersect surface of sphere 6000 at a great circle 30215, as illustrated in FIG. 30B.

As further illustrated in FIG. 30B, great circle 30215 may be at an angle μ₁ to pole 6120. In one or more embodiments, angle μ₁ may be the first bearing. In one or more embodiments, angle μ₁ may be based on the first bearing and an angle of declination. For example, a declination angle (e.g., an offset angle) may be added or subtracted to the first bearing in determining. In one or more embodiments, the declination angle (e.g., the offset angle) may be based on a position on a planet (e.g., Earth). For example, an angular difference (e.g., a declination angle) may exist between a magnetic pole (e.g., a magnetic north pole) and a geographic pole (e.g., a geographic north pole such as pole 6120) depending on a position on the planet (e.g., Earth). For instance, adding or subtracting (e.g., adding a negative number) the angular difference (e.g., the declination angle) to or from the first bearing based on a magnetic pole (e.g., a magnetic north pole) may be utilized in computing a bearing μ₁ (e.g., μ₁ as illustrated in FIG. 30B) that is referenced to a geographic pole (e.g., a geographic north pole such as pole 6120).

In one or more embodiments, a declination angle may vary over an amount of time transpiring. For example, a first declination angle corresponding to a position on a planet (e.g., Earth) on a first date may be different from a second declination angle corresponding to the position on the planet on a second date, different from the first date.

Referring now to FIG. 29, at 29040, a second bearing to an object may be determined. In one or more embodiments, user 5010 may align bearing device 5110 with the object. For example, user 5010, at a second position (e.g., position 9010), may align bearing device 5110 with object 3210. In one or more embodiments, bearing device 5110 may determine a second angle of the object, with respect to a magnetic pole (e.g., a magnetic north pole). In one example, the second angle may be utilized as the second bearing. In another example, the second bearing may be based on the second angle and an angle of declination. In one instance, the second bearing may be computed as a sum of the second angle and the angle of declination. In another instance, adding or subtracting (e.g., adding a negative number) the declination angle to or from the second bearing based on a magnetic pole (e.g., a magnetic north pole) may be utilized in computing a bearing μ₂ that is referenced to a geographic pole (e.g., a geographic north pole such as pole 6120).

At 29050, a second position may be determined. For example, position device 15310 may determine the second position (e.g., position 9010). In one or more embodiments, the second position corresponds to the second bearing. In one example, the second bearing to the object and the second position may be determined simultaneously. In a second example, the second bearing to the object and the second position may be determined concurrently. For instance, at least one portion of determining the second bearing to the object and at least one portion of determining the second position may occur during an amount of time transpiring. In another example, the second bearing to the object and the second position may be determined serially such that an amount of time transpiring does not adversely affect an accuracy of determining the position of the object. For instance, determining the second position may be determined within a foot or two of determining the second bearing. In one example, a system that determines the position of the object may be moving. In another example, a system that determines the position of the object may be stationary.

At 29060, a second vector that is normal to the origin, the object, and the second position may be determined. For example, a vector 31110, as illustrated in FIG. 31A, may be determined as the second vector. For instance, the origin, the object, and the second position may be a basis for a plane 31010, which is illustrated in FIG. 31A as an intersection with sphere 6000. In one or more embodiments, determining the second vector may include utilizing the second bearing. For example, plane 31010 may intersect surface of sphere 6000 at a great circle 31215, as illustrated in FIG. 31B. As further illustrated in FIG. 31B, great circle 31215 may be at an angle μ₂ to pole 6120. In one or more embodiments, angle 912 (e.g., 12 as illustrated in FIG. 31B) may be the second bearing. In one or more embodiments, angle 2 may be based on the second bearing. For example, an offset angle (e.g., a declination angle) may be added or subtracted to the second bearing in determining μ₂.

Referring now to FIG. 29, at 29070, a third vector that is normal to the first vector and the second vector may be determined. In one or more embodiments, determining the third vector may include determining an intersection of planes 30010 and 31010. For example, FIG. 32A illustrates the intersection of planes 30010 and 31010. In one or more embodiments, determining the intersection of planes 30010 and 31010 may include determining a vector cross product of the first vector and the second vector. For example, determining the third vector may include computing a vector cross product of the first vector (e.g., vector 30110) and the second vector (e.g., vector 31110).

At 29080, a position of the object may be determined. In one or more embodiments, determining the position of the object may include determining an intersection of plane 30010, plane 31010, and sphere 6000, as illustrated in FIG. 32A. For example, position 6210 may be determined utilizing the third vector (e.g., a vector 32620 as illustrated in FIG. 32B). For instance, position 6210 may be determined from an intersection of sphere 6000 and the third vector. In one or more embodiments, the third vector may be scaled to a radius of sphere 6000, a radius of Earth, or a radius of Earth plus or minus an altitude. For example, the position of the object (e.g., object 6210) may be determined by scaling the third vector to a radius of sphere 6000, a radius of Earth, or to a radius of Earth plus or minus an altitude. For instance, vector 32620 (e.g., the third vector) may be scaled to a radius of sphere 6000, as illustrated in FIG. 32C as a vector 32630. In one or more embodiments, a radius of sphere 6000 may be scaled to a radius of Earth or a radius of Earth plus or minus an altitude.

In one or more embodiments, the position of the object may be determined to be the third vector or at least a portion of the third vector. For example, the third vector may be a vector in a spherical coordinate system, and the position of the object may be determined to be or to include the angular portions of the third vector. For instance, as illustrated in FIG. 32C, the position of the object (e.g., object 6210) may be determined to be or to include a first angle, θ, to a first reference direction (e.g., a positive x-axis or axis 32610), and a second angle, φ, to a second reference direction (e.g., a positive z-axis or axis 32614). FIG. 32C also illustrates a positive y-axis or axis 32612.

In one or more embodiments, the method illustrated in FIG. 29 may be repeated in determining one or more positions of respective one or more objects. In one example, the method illustrated in FIG. 29 may be repeated to compute position 6220 of a second object (e.g., object 3220). In a second example, the method illustrated in FIG. 29 may be repeated to compute a position 35810 (illustrated in FIG. 35) of a third object (e.g., a windward mark, a point of interest, etc.). In a third example, the method illustrated in FIG. 29 may be repeated to compute a position 35820 (illustrated in FIG. 35) of a fourth object (e.g., a leeward mark, a building, a tower, a structure, etc.).

In a fourth example, the method illustrated in FIG. 29 may be utilized to compute position 6215 utilizing a first position of position 6015 and a second position of position 9015, as illustrated in FIGS. 6B and 9B, respectively. In another example, the method illustrated in FIG. 29 may be utilized to compute position 6217 utilizing a first position of position 6017 and a second position of position 9017, as illustrated in FIGS. 6C and 9C, respectively.

Turning now to FIG. 33, an exemplary method of determining a great are is illustrated, according to one or more embodiments. At 33010, a first position of a first object may be determined. For example, as illustrated in FIG. 35, the first position may be or include position 6210. At 33020, a second position of a second object may be determined. For example, as illustrated in FIG. 35, the second position may be or include position 6220.

At 33030, a great are bounded by the first position and the second position may be determined. For example, as illustrated in FIG. 35, a great arc 35310 bounded by position 6210 and position 6220 may be determined. In one or more embodiments, great arc 35310 may be or include a portion of a great circle that includes positions 6210 and 6220, where positions 6210 and 6220 may be boundaries of the portion of a great circle that includes positions 6210 and 6220.

Turning now to FIG. 34, an exemplary method of determining a plane is illustrated, according to one or more embodiments. In one or more embodiments, method elements 34010 and 34020 may be performed with respect to method elements 33010 and 33020, respectively. At 34030, a plane may be determined, utilizing the first position and the second position. For example, an origin (e.g., an origin of sphere 6000), the first position, and the second position may be or include a basis for a plane 36010, which is illustrated as an intersection with sphere 6000 in FIG. 36.

In one or more embodiments, determining the plane (e.g., plane 36010) may include computing a vector cross product of a first vector associated with the first position (e.g., position 6210) and a second vector associated with the second position (e.g., position 6220). For example, the vector cross product of the first vector associated with the first position and the second vector associated with the second position may be or include a vector 36110. For instance, vector 36110 may be normal to plane 36010.

In one or more embodiments, determining the plane (e.g., plane 36010) may include utilizing the first position (e.g., position 6210), the second position (e.g., position 6220), and an origin (e.g., the origin of sphere 6000). In one example, position 6210, position 6220, and the origin of sphere 6000 may form a basis for plane 36010. In a second example, plane 36010 may be determined such that plane 36010 includes position 6210, position 6220, and the origin of sphere 6000.

Turning now to FIG. 37, an exemplary method of determining a distance is illustrated, according to one or more embodiments. At 37010, a position may be determined. For example, position device 15310 may determine the position (e.g., a position of positions 35410-35430 illustrated in FIG. 35). In one example, a system that determines the position of the object may be moving. For instance, position device 15310 may be moving. In another example, a system that determines the position of the object may be stationary. For instance, position device 15310 may be stationary. In one or more embodiments, being stationary may include not changing a position, within a coordinate system, within an amount of time transpiring. For example, being stationary may include not changing a position, within an ECEF coordinate system, within an amount of time transpiring.

At 37020, a distance from the position to a great are may be determined. For example, a distance from a position of positions 35410-35430 to great arc 35310, as illustrated in FIG. 35, may be determined. In one or more embodiments, great arc 35310 may be or include starting line 3310 and/or a finish line.

Turning now to FIG. 38, an exemplary method of determining a distance to a plane is illustrated, according to one or more embodiments. At 38010, a position may be determined. For example, position device 15310 may determine the position (e.g., a position of positions 36410-36430 illustrated in FIG. 36). In one example, a system that determines the position of the object may be moving. In another example, a system that determines the position of the object may be stationary.

At 38020, a distance from the position to a plane may be determined. For example, a distance from a position of positions 36410-36430 to plane 36010, as illustrated in FIG. 36, may be determined. In one or more embodiments, plane 36010 may include starting line 3310 and/or a finish line.

In one or more embodiments, a distance from the position to the plane may be determined by projecting a vector from an origin (e.g., the origin of sphere 6000) to the position (e.g., a position of positions 36410-36430) onto the plane (e.g., plane 36010). For example, projecting the vector onto the plane may include determining a vector dot product (e.g., an inner product) of the vector, from the origin to the position, and vector 36110 (e.g., a vector that may be utilized to describe plane 36110).

In one or more embodiments, vector 36110 may not be a unit vector, and projecting the vector onto the plane may include determining a magnitude of vector 36110. In one example, the vector dot product of the vector, from the origin to the position, and vector 36110 may be divided by the magnitude of vector 36110. In another example, the vector dot product of the vector, from the origin to the position, and vector 36110 may be multiplied by a reciprocal of the magnitude of vector 36110.

In one or more embodiments, the distance from the position to the plane may be sufficient to determine a distance from the position to starting line 3310, a finish line, and/or great arc 35310. For example, plane 36010 may include starting line 3310 (as illustrated in FIG. 3), the finish line, and/or great arc 35310 (as illustrated in FIG. 35). In one instance, a difference of the distance from the position (e.g., a position of positions 36410-36430) to plane 36010 and a measure of a great arc (of sphere 6000) from the position to plane 36010 may be negligible. For example, the difference that may be negligible may be less than or equal to a radius of uncertainty of position device 15310. In one or more embodiments, if difference is negligible, less computations may be performed, and/or a processor of low computing power processor (e.g., a processor that does not include a floating point unit) may be utilized in determining a distance from the position to starting line 3310, the finish line, and/or great are 35310.

Turning now to FIG. 39A, an exemplary method of determining, utilizing a first bearing from a first position to an object at a second position, a first great circle intercept is illustrated, according to one or more embodiments. At 39010, a first bearing from a first position to an object may be determined. For example, the first bearing may be angle μ₁. For instance, angle μ₁ may be computing is a same or similar fashion as described above. For example, μ₁ may be based on a declination angle.

At 39020, a first result of a tangent function of μ₁, may be determined. For example, determining the first result of a tangent function of μ₁ may include computing a tangent function of μ₁ (e.g., tan(μ₁)). At 39030, a second result of Position_(1φ)subtracted from

$\frac{\pi}{2}$

may be determined, where Position_(1φ)is the φ component of the first position expressed in a spherical coordinate system. For example, determining the second result of Position₁, subtracted from

$\frac{\pi}{2}$

may include computing a result of

$\frac{\pi}{2} - {{Position}_{1\varphi}.}$

At 39040, a third result of a sine function of the result determined at 39030 may be determined. For example, determining tile third result of tile sine function of the second result, determined at 39030, may include computing a result of the sine function of the second result, determined at 39030. For instance,

$\frac{\pi}{2} - {Position}_{1\varphi}$

may be computed as the third result.

At 39050, a fourth result of the third result multiplied by the first result may be determined. For example, determining the fourth result may include computing the third result multiplied by the first result. For instance, the fourth result may be determined by computing

${\tan \left( \mu_{1} \right)} \cdot {{\sin \left( {\frac{\pi}{2} - {Position}_{1\varphi}} \right)}.}$

At 39060, a fifth result of an inverse tangent function of the fourth result may be determined. For example, determining the fifth result may include computing an inverse tangent function of the fourth result. For instance, the fifth result may be determined by computing

${\tan^{- 1}\left( {{\tan \left( \mu_{1} \right)} \cdot {\sin \left( {\frac{\pi}{2} - {Position}_{1\varphi}} \right)}} \right)}.$

At 39070, a sixth result of the fifth result subtracted from Position_(1φ)may be determined, where Position_(1φ)is the θ component of the first position expressed in a spherical coordinate system. For example, determining the sixth result of the fifth result subtracted from Position_(1φ)may include computing

${Position}_{1\varphi} - {{\tan^{- 1}\left( {\tan {\left( \mu_{1} \right) \cdot {\sin \left( {\frac{\pi}{2} - {Position}_{1\varphi}} \right)}}} \right)}.}$

At 39090, a first angle of the great circle intercept may be established. For example, the first angle of the great circle intercept may be established as the sixth result. For instance, the first angle of the great circle intercept may be set to the sixth result (e.g.,

$\left. {{GreatCircleIntercept}_{1\; \theta} = {{Position}_{1\; \theta} - {\tan^{- 1}\left( {{\tan \left( \mu_{i} \right)} \cdot {\sin \left( {\frac{\pi}{2} - {Position}_{1\; \varphi}} \right)}} \right)}}} \right).$

At 39080, a magnitude of the great circle intercept may be established. In one example, the magnitude of the great circle intercept may be established as a radius of a sphere or a radius of Earth. For instance, the magnitude of the great circle intercept may be set to the radius of the sphere (e.g., sphere 6000) or the radius of Earth. In another example, the magnitude of the great circle intercept may be established as a unit value. For instance, the magnitude of the great circle intercept may be set to one.

In one or more embodiments, setting the magnitude of the great circle intercept to one (e.g., unity) may simplify (e.g., reduce) and/or eliminate one or more computations.
